Sendmail Problem
1) smsabc.co.tt (192.168.9.120) >> my host
2) relay.operator.co.tt >> 10.20.2.31 relay server
3) I would like to send to yyy@operator.co.tt, what should I do?
4) look up at file only.

Re: Sendmail Problem
I would check (or have your mail admins check) that the relay host 10.20.2.31 is configured to allow 192.168.9.120 to use it as a relay.
The fact you can't ping it is most likely to be a firewall rule, and I don't think has any bearing on the email issue.

Re: Sendmail Problem
I remember having the "Service unavailable" error some while ago. If I remember correctly, it was caused by the relay server (which was Lotus Notes) not being configured to allow my UNIX host to use it as a relay. This is generally configured to close open relays to refuse spam.

Re: Sendmail Problem
Are you using DNS?
try to telnet to port 25 on the relay server and send from command line.

Re: Sendmail Problem
telnet localhost 25
and network status as,
netstat -na | grep -w 25
one as LISTEN status there.
To lookup about the hostname resolvation you have to use nslookup / nsquery command.
nslookup smsabc.co.tt
nslookup relay.operator.co.tt
If you want to make it with files entry then,
---/etc/nsswitch.conf file---
hosts: files dns
-- /etc/hosts file --
Now check lookup as,
nsquery hosts
You have to be succeeded.
